A A 70-year-old man has had increasing difficulty with movement, starting with his feet and ascending to involve legs, trunk, and now arms, over the past 10 days. On physical examination there are variable sensory changes noted. He is afebrile. He does not lose consciousness and remains mentally alert. He becomes ventilator dependent a week after the onset of this illness. A lumbar puncture is performed and the CSF demonstrates a protein of 86 mg/dL, glucose 63 mg/dL (serum 89 mg/dL), and only 3 mononuclear cells/microliter. He gradually recovers over the ensuing 4 weeks. Which of the following conditions most likely preceded the onset of this man's illness?

(B) CORRECT. This rapidly ascending paralysis is Guillain-Barré Syndrome, or acute idiopathic polyneuritis. About 75% of cases are associated with a history of a prior viral infection. An immunologic mechanism for this disease is suspected.

B.

Approximately two-thirds of cases are preceded by an acute, influenza-like illness from which the patient has recovered by the time the neuropathy becomes symptomatic. Infections with Campylobacter jejuni, cytomegalovirus, Epstein-Barr virus, and Mycoplasma pneumoniae have been shown to have a significant epidemiologic association with Guillain-Barré syndrome
